First, convert a mixed fraction to an improper fraction.

Use division.

for example, If we distribute 100 candies such that each pupil is getting 20 candies then how many pupils are there?

You need to calculate for each one. However eastimation is a quick way to work with.

How many metres are in a km?

Divide as usual. Put the decimal point in the quotient directly above where the decimal point now is in the dividend.

To divide a fraction by any whole number means, multiply that fraction by the reciprocal of that whole number.

We can't cancel down a division, but we can cancel it down once it has changed into a multiplication.

Divide the given number and place the decimal accordingly.
